Shell’s opens new tab emissions were largely stable in 2025 at around 1.1 billion metric tons of CO2 equivalent, according to its annual report published on Thursday and Reuters calculations.
The bulk of the energy major’s emissions come from so-called Scope 3 emissions based mainly on the combustion of the fuel a company sells. In comparison, Britain’s emissions stood at around 480 million tons of CO2 equivalent in 2024.
Net carbon intensity (NCI), the main measure the group uses for its energy transition strategy, stood at 71 grams of CO2 equivalent per megajoule, unchanged from 2024, said Shell, which wants to reduce this measure to zero by 2050.
Measuring emissions performance by intensity means a company can technically increase its fossil fuel output and overall emissions while using offsets or adding renewable energy or biofuels to its p
